K deaktivaci slabého šifrování použijte PowerShell

Tento článek vám pomůže deaktivovat určité protokoly, aby prošly kontrolami shody platebních karet (PCI) pomocí Windows® PowerShell®.

Následující blok skriptu obsahuje prvky, které deaktivují mechanismy oslabení šifrování pomocí úprav registru. Podrobnosti najdete v komentářích k bloku skriptů. Po spuštění jakéhokoli prvku skriptu musíte restartovat server Windows, aby se změny plně projevily.
